General
Non-programmable heat pump thermostats are wall-
mounted, low-voltage thermostats that maintain
room temperature by con trolling the operation of
heat pump systems. A variety of features are provided
including sepa rate heating and cooling set points, auto
changeover, keypad lockout, back lighting, and built-in
installer test.
Figure 1: Non-Programmable Heat Pump Thermostat
This Installation Instruction covers installation,
configuration, and start up of the non-programmable heat
pump thermostat.
This manual is intended for installer and owner only.
Package Contents
1 - Thermostat
1 - Backplate (mounting base with terminal strips)
2 - Screws and anchors
3 - User Operating Manual (review with end user)
Installation Considerations
Power
- 24 volt AC (50/60 Hz) power via the Rc/Rh and C
terminals. Rc and Rh terminals are connected via factory-
installed jumper wire.
Wiring
-
Requires 6 conductor thermostat cable for 2 fan
speed units. The wire length should be no more than 250
ft (76 m). Use 22 AWG (American Wire Gage) for normal
wiring applications. Continuous wire lengths over 100 ft
(30.5 m) should use 20 AWG or larger.
Reconfigure if unit is only 1 fan speed, see option 40.
Note: This thermostat has battery compartment but is
non-operational and must be wired.
Thermostat Location
—
The thermostat should be mounted:
• approximately 5 ft (1.5 m) from the floor
• in the conditioned space, preferably on an inside wall
on a section of wall without pipes or ductwork
The thermostat should NOT be mounted:
• close to a window, on an outside wall, or next to a
door leading to the outside
• where exposed to direct light and heat or any other
temperature-radi ating object which may cause a false
reading
• close to or in direct airflow from supply registers or
return air grille in areas with poor air circulation.
